What is Bootstrap?

Bootstrap is a huge collection of reusable pieces of code which can be quite handy to the developers. It is a Frontend-Development Framework, written in HTML, CSS and JavaScript. Bootstrap enables designers and developers to build completely responsive websites quickly. It can be considered as the most popular CSS Framework for developing responsive and Mobile-First applications. Main features of Bootstrap may be described up as follows :

  • Bootstrap is a free front-end framework, with a purpose to make web development faster and easier.
  • It also includes HTML and CSS based design templates for forms, typography, buttons, navigation, tables, modals, image carousels and many other components along with other optional JavaScript plugins.
  • Bootstrap also provides the users the ability to easily create responsive designs.
  • The responsive CSS of Bootstrap also adjusts to phones, tablets, and desktops easily.
  • It is compatible with all modern browsers like Chrome, Firefox, Internet Explorer, Edge, Safari, and Opera.


Bootstrap provides a whole barrelful of components which can be easily included onto our web applications, like :

  • Dropdowns
  • Forms
  • Navigation Bars
  • Buttons
  • Tables
  • Progress bars
  • Thumbnails

Therefore, adding eye-catching design elements to our applications is very easy and we can be assured that all of the components will look awesome no matter the screen size or device used to view them. Thus, it provides a lot of ready-made functionalities at the fingertips.

Responsive Grid

Bootstrap has its own grid system predefined. We can get straight to filling your containers with required content.

Users can define certain custom breakpoints for each column, using their extra small, small, medium, large, and extra large breaks. It also has a default option which can be used in most of the scenarios. Thus, the responsive grid of this framework makes the life of developers easy.

Time Saving

When we are bound to an extremely confined timeline to build a web application or a mobile application, we can easily take advantage of Bootstrap framework and nail our project effortlessly. It is due to the ready-made blocks which are built ready for us to use them. Evidently, we do not have to start everything from scratch, and can modify certain elements to make it unique with the inputs.

When we download and install Bootstrap, it unpacks ready-made themes & templates. We can choose from it or can also choose to include inputs from other sources. But, we must also be aware that there are a lot of people who do the same. Hence, to look unique from the rest of the websites that have the same theme or template, we need to get a little creative and modify certain components such that it defines our website or application uniquely.


Users can always modify the CSS file if they are not satisfied with Bootstrap’s design template. Also, it can be combined with existing designs and thus, they can complement each other’s functions. It is very much helpful when we want to give our application a unique look but we do not have enough time to learn or code custom CSS from scratch.

By using Bootstrap’s customization page, we can tweak it further to create your own custom theme. We must also identify and remove all the plugins and components that is not required for the web project. Moreover, we also get to have a specific section where we can customize our template by changing the values to the variables.


Bootstrap framework also comes with compatibility. The Bootstrap development team assures the compatibility of the framework with all modern browsers, versions and platforms. This framework don’t support proxy browsers and older browsers, but that doesn’t affect its display or functionality.


There have been certain inconsistencies prevailing between the Front-end and Backend development teams. The creators of Bootstrap wanted to come up with a solution to establish consistency among these teams. Therefore, they developed this Bootstrap framework that eradicates the use of libraries that differ from developer to developer. So, as a result, no matter who handles the project, the framework establishes consistency throughout the project. Since it is also compatible across multiple browsers, no matter what browser we use for our development purpose, it consistently produces the same output across all browsers.

Community Support

Bootstrap provides a lot of resources and materials on their official website and some other websites also offer certain resources that would facilitate the front-end development process. Along with that, the official website also offers incredible documentation which makes creating a website, a lot simpler. Moreover, we can get access to their templates and themes to which we can make required changes.

Since the Bootstrap community is huge, if we are stuck with any complex error and we could not figure out why it is happening using Google, we can always post a question where the expert developers having the same issues might help us out.

Are there any Drawbacks?

  1. Sometimes, there might be certain requirements of variety of style overrides or rewriting files that can thus lead to a lot of time spent on designing and coding the website if the design tends to divert from the original design used in Bootstrap.
  2. We may have to go the extra mile while creating a design otherwise all the websites will look the same if we don’t do heavy customization.
  3. Styles are verbose and can lead to lots of output in HTML which is not needed.


  • In this article, we learnt about that, Bootstrap is a powerful CSS framework that has taken over web development, especially the front-end development, and community to the next level.
  • We also understood that it enhances the development process by offering resources such as templates and themes, which can be customized according to the project needs.
  • Since Bootstrap is an open-source framework, we can modify it without spending anything.
